Has the beholder been raised from the dead, much like this thread? This was answered long ago in Sage Advice. Short answer? Antimagic zone has no effect, any more than a dragon's breath weapon.
Determining whether a game feature is magical is straightforward. Ask yourself these questions about the feature:
- Is it a magic item?
- Is it a spell? Or does it let you create the effects of a spell that’s mentioned in its description?
- Is it a spell attack?
- Is it fueled by the use of spell slots?
- Does its description say it’s magical?
